Batteries; as a result of electrochemical reactions occurring in which is used to store electrical energy and use it when necessary. are systems. Batteries are negative batteries with different types, properties and purity values. electrode (anode), positive electrode (cathode), electrolyte liquid and connection (tab) formed by the combination of points. The ports (tab) are on a single battery or positive and negative poles on each battery cell in the battery pack. They are electrically conductive bridges that are located and current flowing over them. Battery By making serial and parallel connections from the connection points, electric vehicle Energy is supplied to many systems such as applications. Experimental in the literature and numerical studies show that the highest temperature values in battery systems occur at the connection points, through which high-density current flows. has made it clear that he has arrived. The excess of the batteries the battery, especially the safety issues such as fire and explosion, effect on many situations such as performance, battery life, fast charging feature. are available.

Bataryalardaki isinma kritik degerlerin üzerine çiktiginda olusan zincir reaksiyonlar ile deformasyon, yangin ve patlama riskleri ortaya çikmaktadir. Bu noktada, isinmanin kritik seviyelerin altinda tutulmasi, güvenlik riskinin ortadan kaldirilmasi ve homojen sicaklik dagiliminin elde edilmesi adina batarya isil yönetim sistemleri (BlYS) gelistirilmistir. Literatürde, batarya isil yönetim sistemlerine dair çok sayida numerik ve deneysel çalisma bulunmaktadir. The chain formed when the heating in the batteries exceeds the critical values. Risks of deformation, fire and explosion occur with reactions. This At this point, keeping the heating below critical levels will eliminate the security risk.

Özellikle yüksek enerji gerektiren sistemlerde yukaridaki çiktilari elde etmek amaciyla batarya isil yönetim sistemleri (BIYS) gelistirilmistir. Bu sistemlerdeki en büyük eksik ise, en yüksek sicakliklarin yüksek akim yogunluguna bagli olarak ölçüldügü baglanti noktalarindan herhangi bir isi transferi öngörmeden yalnizca batarya yüzeylerinden sogutma saglamasidir. Gerek deneysel gerekse de sayisal çalismalar batarya yüzeylerinden yapilacak sogutma tasarimi ile batarya ve batarya paketinde sicaklik dagiliminin baglanti noktalarina yakin kisimlarda daha yüksek degerlere sahip olacak sekilde olustugunu ortaya koysa da, baglanti noktalarinin elektrik akiminin geçtigi noktalar olmasi sebebiyle bu noktalara herhangi bir isil sistem tasarimi ortaya konamamistir. Bunun nedeni, elektriksel güvenligin saglanamamasi ve kaçak riskinin bulunmasidir. Electric vehicle technologies, energy storage systems and defense industry which is in the main investment area in many fields such as the The main problem in battery/battery pack systems is to obtain homogeneous temperature distribution. to create a safe, high-performance and sustainable energy system. To achieve the above outputs, especially in systems that require high energy For this purpose, battery thermal management systems (BIYS) have been developed. in these systems the biggest shortcoming is due to the high current density of the highest temperatures without foreseeing any heat transfer from the ports where it is measured as it only provides cooling from the battery surfaces. Both experimental and Numerical studies will be carried out from the battery surfaces with the cooling design. close to the junction points of the temperature distribution on the battery and battery pack Even if it reveals that it is formed in a way that will have higher values in the parts Also, this is because the connection points are the points where the electric current passes. No thermal system design has been put forward to the points. This is because, electrical safety cannot be provided and there is a risk of leakage.
